Subject: Application for leave for going out of the city.
Most respectfully, I would to state to you that I am a student of your school. I am a student in the 10th class. My family today decided to go out of the city for visiting a relative who is seriously ill. Hence I will not be able to attend classes today.
I kindly request you to consider my request and grant me one day’s leave for which I shall be always grateful.
Thank you in hope.
